01
Make
Put every demand item through one front door. Compare it against declared criteria, finite capacity and the work it would displace.
Independent decision governance practice · Hong Kong
Decide before you build.
MONO360 puts a governed front door on enterprise change—so work earns its place before it enters the plan, and the decision can still be reproduced a year later.

01 / The governed loop
Most enterprises can show what was approved. Far fewer can reproduce why it won, what it displaced, whose judgement mattered, or what happened next.
02
Explain
Keep the evidence, assumptions, alternatives, trade-offs and accountable names alongside the decision—not scattered through slides and inboxes.
03
Challenge
Design gates that can fail. Preserve disagreement, expose confidence gaps and show where judgement—not evidence—made the difference.
04
Retain
Hold every decision as a versioned record: who decided, under which rule, using which data, accepting which risk, at that moment in time.
05
Learn
Revisit the original promise. Compare forecast with outcome, test the assumptions and carry the learning into the next allocation.
02 / What changes
Governance becomes evidence.
Reproduce the decision.
A durable record of the alternatives, evidence, assumptions, challenge and accepted risk behind every consequential investment.
Attention goes where confidence breaks.
Reported confidence and computed evidence are allowed to disagree. The gap becomes a board question.
A name against every signature.
Decision rights stay explicit—especially where AI recommends and a person remains accountable.
The portfolio learns from what it funded.
Benefits and outcomes close the loop. Future choices inherit evidence, not folklore.
03 / The method, productised
Meet Horizon PMO.
The executive decision layer that sits across the systems you already run—holding the live portfolio, the governing rules and the history of every call.
Selected views show where attention is required, what a decision changes and the evidence behind the answer.

Which assumption changes this decision first?
MAIA / explained answer
Adoption confidence is doing more work than the evidence supports.
Atlas falls below the approval threshold if adoption is under 63%. Two sources still use the unvalidated 78% assumption.

04 / Questions we are asked
Before we begin.
Do we have to replace our existing tools?
Usually not. MONO360 starts with the portfolio evidence and systems already in use. Reliable sources can stay; conflicts, gaps and missing controls are made explicit. Horizon PMO can sit above the estate when a governed decision layer is needed, but the advisory work does not depend on buying the platform.
We already have a PMO. When does MONO360 add value?
When demand enters before governance, evidence is split across systems, or a consequential decision cannot be reproduced afterwards. If your PMO already owns the front door, preserves the evidence and retains accountable decision history, MONO360 may add limited value.
What do we actually buy?
The first offer is advisory: a read of the portfolio you already have and the design of the gates, decision rights and evidence model it needs. Where software is useful, Horizon PMO provides the governed decision layer. The advisory recommendation remains independent of the platform.
Where does AI sit—and where does it stop?
AI can read permitted evidence, draft, explain, score and challenge. It does not approve a decision or silently change the accountable record; a named person remains responsible for the call. The exact data access, approval controls and integrations are confirmed for each engagement.
How does an engagement start?
With one consequential decision, a named owner, an agreed evidence set and explicit success measures. We inspect the portfolio and systems as they are—not a theoretical future state—and produce evidence for or against wider change.
Are you an alternative to the large consulting firms?
Not as a general substitute for delivery scale. MONO360 is an independent specialist in the decision before and through delivery: what should enter the portfolio, under which rule, with whose approval and with what evidence retained. We can work before, alongside or independently of a larger delivery partner.
Is this an AI transformation programme?
Not by default. The work can support an AI transformation, but its focus is the operating model that decides what gets built, who signs and what is retained. It can stand alone wherever enterprise-change decisions need stronger governance. See the five foundations →
Start with a real decision
Can yours be reproduced?
Bring us one consequential portfolio call. We’ll trace what exists, what is missing and what the enterprise can learn from it.
